Our dear colleague Joel I. Seiferas retired on December 31, 2016,after more than 37 years at the University of Rochester's Departmentof Computer Science, and became professor emeritus of computerscience.

The talks are all free and open to the public, and we very much hopeyou will attend them. The web page

has the information (schedule, travel, lodging, etc.) on the event,and on how to register (**please register by August 22nd** so we knowhow many will attend and can get right the room size for the talks;registering is about a 1-minute process), and on how---if you won't beable to attend but would like to send a message for Joel to be givenon that day---to do so.
